What is the primary purpose of using a suction cup for RGP lens removal?

• A. To create a vacuum seal
• B. To enhance grip
• C. To alleviate dryness of the eye
• D. To minimize lens warping

Answer: (B)

Using a suction cup for the removal of rigid gas permeable (RGP) lenses primarily serves to enhance grip. The design of a suction cup allows for effective contact with the lens surface, enabling the practitioner or user to securely grasp the lens. This grip is crucial as RGP lenses can adhere to the eye due to the natural moisture and contour of the cornea, making them sometimes tricky to remove. By enhancing grip, the suction cup allows for a smooth and controlled removal process, minimizing the risk of discomfort or damage to the lens and the eye. While other factors such as minimizing lens warping or creating a vacuum seal may play roles in specific circumstances, the enhanced grip is the fundamental purpose that addresses the challenges associated with RGP lens removal. This ensures that users can maintain comfort and safety while handling their lenses.
